- You run a food bar in UCLA Ackerman, and you sell chocolate croissants for breakfast. Your daily demand for chocolate croissants is on average 50, with a standard deviation of 8. The unit cost of a croissant is $0.70, and you sell at a unit price of $3.00. The refrigerated chocolate croissant must be consumed within 7days (one week) after purchased from your supplier, so you dispose leftover inventory and purchase fresh croissants once every week. Assume the demand in each of the seven days is independently distributed. (The z-table for normal distribution is attached.) (a) What is the optimal weekly purchase quantity for the chocolate croissant? What is average inventory? A student leader, Mark, came to you one day and told you that Anderson School would hold a special event next Thursday morning, and there would be additional demand for the chocolate croissant on that day. Mark wants to reserve a certain amount of croissant from you and sell in the special event at the regular price.…arrow_forwardAn oil refinery buys crude oil on a long-term supply contract for $22.50 per barrel.When shipments of crude oil are made to the refinery, they arrive at the rate of10,000 barrels per day. The refinery uses the oil at a rate of 5,000 barrels per dayand plans to purchase 500,000 barrels of crude oil next year. If the carrying cost is25percent of acquisition cost per unit per year and the ordering cost is $7,500 perorder:a. What is the EOQ for the crude oil?b. What is the TSC at EOQ?c.

- Drug Inc. sells a high runner product that is ordered every 20 days when a sales person visits from one of the pharmaceutical companies. This product has an average daily demand of 1,500 units. The standard deviation of daily demand was calculated from evaluating data over the past three months and was found to be 550 units. Once an order is started, it takes seven days to arrive. The company would like to satisfy 95 percent of their demand. The sales person just arrived, and there are currently 10,000 units in warehouse. How many units should be ordered during that Time Period? Formula = Reorder point (time period) – On hand inventoryarrow_forward3) A company produces a part that is used in its production process. The company produces the part at a rate of 300 units per day. The daily demand for the product is 180 units. The annual demand for the part is 54,000 units and occurs consistently over the 300 days that the company operates yearly. The company incurs a setup cost of $300 each time the item is produced. The cost of carrying the item in inventory is estimated to be 25 percent of the item's $100 cost. How many units should the company produce each production run to minimize its inventory- associated costs?arrow_forwardConsider a fixed period inventory model. The daily demand of the product has a mean of 30 and standard deviation of 4; orders are placed every 18 days and shipment lead time is 6 days. The store has a service policy of 96%.

- You have been asked to help a manufacturing firm that produces a variety of specialty components for local auto speed shops. The firm orders a number of components from suppliers, but the one they have asked you to analyze is special welding rod. Historical data suggests daily consumption of these rods can be modeled by a normal distribution with a mean and standard deviation of 42.3 and 5.1 bolts per day, respectively. The rods come in boxes of 5 rods/box, and the supplier will only ship in box quantities. It takes 2 days to receive an order from the supplier. You may assume that the daily demands are independent and identically distributed, and that inventory position is always known (i.e., continuous review). 1. The current policy is the order thirty boxes from the supplier when inventory position reaches ten boxes. What is the long run fraction of stock outs associated with the current strategy? 2.

The airline knows from history that an average of 28 customers (with a standard deviation of 14) cancel their reservation or do not show for the flight. Revenue from a ticket on the flight is $122. If the flight is overbooked, the airline has a policy of getting the customer on the next available flight and giving the person a free round-trip ticket on a future flight. The cost of this free round-trip ticket averages $228. Super Discount considers the cost of flying the plane from New York to Los Angeles a sunk cost. By how many seats should Super Discount overbook the flight? Note: Use Excel's NORM.S.INV function to find the z value. Round z value to 2 decimal places.
